I'm using EM7565 in MBIM mode. Please see below snippets from log which highlight the delay. As you can see "couldn't load carrier config; couldn't load SUPL; assistance data" are causing this slowness. MM 1.12.6 or MM 1.14.0 + libmbim 1.24.0 Jul 7 11:42:59 [6570]: <info> [modem0] QMI-based capability and mode switching support enabled Jul 7 11:43:04 [6570]: <warn> [modem0] couldn't load carrier config: Operation timed out Jul 7 11:43:05 [6570]: <warn> [modem0/sim0] couldn't load list of emergency numbers: Failed to parse CRSM query result '+CRSM: 148,8,""' Jul 7 11:43:15 [6570]: <warn> [modem0] couldn't load SUPL server: Failed to receive indication with the current server settings Jul 7 11:43:25 [6570]: <warn> [modem0] couldn't load supported assistance data types: Failed to receive indication with the predicted orbits data source Jul 7 11:43:25 [6570]: <info> [modem0] state changed (unknown -> disabled) MM 1.12.6 + libmbim 1.22.0 Jul 7 11:38:45 [6529]: <info> QMI-based capability and mode switching support enabled Jul 7 11:38:46 [6529]: <warn> couldn't load list of Emergency Numbers: 'Failed to parse CRSM query result '+CRSM: 148,8,""'' Jul 7 11:38:46 [6529]: <info> Modem: state changed (unknown -> disabled) Bearer connection is also slow with libmbim 1.24.0.
